utypes.h
Basic definitions for ICU, for both C and C++ APIs.
U_I18N_API
#define U_I18N_API
Definition: utypes.h:301
UBool
int8_t UBool
The ICU boolean type, a signed-byte integer.
Definition: umachine.h:269
format.h
C++ API: Base class for all formats.
icu::UnicodeString
UnicodeString is a string class that stores Unicode characters directly and provides similar function...
Definition: unistr.h:295
icu::UObject
UObject is the common ICU "boilerplate" class.
Definition: uobject.h:223
UClassID
void * UClassID
UClassID is used to identify classes without using the compiler's RTTI.
Definition: uobject.h:96
UErrorCode
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
Definition: utypes.h:415
icu::StringEnumeration
Base class for 'pure' C++ implementations of uenum api.
Definition: strenum.h:61
icu::UObject::getDynamicClassID
virtual UClassID getDynamicClassID() const
ICU4C "poor man's RTTI", returns a UClassID for the actual ICU class.
icu::NumberingSystem
Defines numbering systems.
Definition: numsys.h:60
uobject.h
C++ API: Common ICU base class UObject.
icu::Locale
A Locale object represents a specific geographical, political, or cultural region.
Definition: locid.h:195
icu::kInternalNumSysNameCapacity
constexpr const size_t kInternalNumSysNameCapacity
Size of a numbering system name.
Definition: numsys.h:42
